High-Def Digest: With Marvel's 'The Avengers' landing on the big screen just one year from now, two of its main players have yet to debut on the big screen. Iron Man and The Hulk have been well established; this summer we meet Thor and Captain America. Following the lead of Christopher Nolan's 'Batman' films, Marvel has set their superheroes in the realistic world. To better achieve a realistic tone, the filmmakers hired accredited stunt coordinator Andy Armstrong to bring 'Thor' from the Godly realm of Asgard to the believable reality in which we are grounded. HDD's own Luke Hickman spoke with Armstrong about his work.
